With tensions between the US and Iran on the rise following the downing of a US military drone last week, the director of the Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency is warning that Iran is elevating its efforts to do damage to US interests through destructive malware attacks on industrial and government networks.
In a statement issued on Saturday, June 22, CISA Director Christopher C. Krebs said:
CISA is aware of a recent rise in malicious cyber activity directed at United States industries and government agencies by Iranian regime actors and proxies. Iranian regime actors and proxies are increasingly using destructive “wiper” attacks, looking to do much more than just steal data and money. These efforts are often enabled through common tactics like spear phishing, password spraying, and credential stuffing. What might start as an account compromise, where you think you might just lose data, can quickly become a situation where you’ve lost your whole network.
Krebs urged businesses and agencies to take steps to improve their security hygiene, including implementing multi-factor authentication for user credentials to prevent brute-force attempts to connect to exposed network and cloud applications.
